Question

no3- lone and bond pair drive with formula

Answer 1

Answer:

in $no^-_3$

Due to the presence of one negative charge, number of valence electrons=5+1=6.

One O-atom forms two bonds (= bond) and two O-atom are shared with two electrons of N-atom

Thus, 3 O-atoms are shared with 8 electrons of N-atom.

Number of bond pairs (or shared pairs)=4

Number of lone pairs =0

Answer 2

Answer:

lone pairs -0

bond pairs-4
